Shibboleth SP logo.jpg missing from distributions

Have you recently installed the Shibboleth SP software and found that the error pages the software is generating are missing the Shibboleth logo? If so, it’s because those error pages are attempting to display a logo (typically /shibboleth-sp/logo.jpg by default) but the logo of the Griffin that you may have been used to seeing is no longer distributed with the software.

Unfortunately, this change doesn’t appear to be documented (yet), but is highlighted in this discussion: http://shibboleth.1660669.n2.nabble.com/Shibboleth-logo-in-Red-Hat-RPM-tp7583386.html

Either my Dell Optiplex 990 computer or my Linux install has an issue: occasionally, when I re-plug a USB device into the system, it’ll cause a fault in the USB module in the kernel and USB goes dark.

Cherokee is a fast web server and something I’m looking at using instead of my current Apache installs in order to squeeze a bit (lot) more juice out of my web services.

You can easily install Cherokee via its automated scripting and that’s really useful.  Unfortunately, since I’m within a RedHat environment, init scripts and other useful aspects that come packaged with Apache don’t get installed when installing from source. Now, there’s a lot of activity regarding installing the latest packages for Ubuntu, but not much of anything recent for RHEL (current Cherokee is 1 …

Apache: Directories and trailing slashes

Apache does something interesting (yes, I still think it’s logical) when you’re accessing a directory that it’s serving: if you access it without a trailing slash, it’ll add one by default. This makes sense if you’re going after some static content or a folder index (or pretty much any sane usage) but it didn’t fit my use case of serving Plone using rewrite rules in a .htaccess file.

The issue that arises for myself with Plone is that my sites need to have their access customised through that .htaccess file and that’s been …
